Quick answer: When you sell your main home, you can exclude up to $250,000 of gain from tax if you’re single, or up to $500,000 if you’re married filing jointly. To qualify, you must have owned the home and lived in it as your primary residence for at least 2 of the 5 years before the sale. Gain above the exclusion is taxed at capital gains rates.
Key facts:
- Maximum excluded gain: $250,000 (single) or $500,000 (married filing jointly)
- You must have owned AND used the home as your primary residence for 2 of the last 5 years
- You generally can’t use the exclusion more than once every 2 years
- Gain above the exclusion is taxed at long-term capital gains rates
- These amounts are not inflation-indexed — they haven’t changed in years
This is the Section 121 exclusion, and it’s one of the biggest tax breaks most homeowners will ever use. It was not changed by the One Big Beautiful Bill Act, so the 2026 figures are the same long-standing amounts.
How much home-sale gain is tax-free in 2026?
For 2026, you can exclude up to $250,000 of gain on the sale of your primary residence if you file single, and up to $500,000 if you’re married filing jointly. Note that the exclusion applies to your gain — roughly your sale price minus what you paid plus certain improvements — not to the full sale price.
| Filing status | Maximum excluded gain |
|---|---|
| Single | $250,000 |
| Married filing jointly | $500,000 |
These figures are not adjusted for inflation and have stayed the same for many years — so don’t treat them as a “new for 2026” number. What makes the exclusion valuable is that home appreciation up to those limits escapes tax entirely, provided you meet the ownership and use tests below.
What is the 2-of-5-years test?
The 2-of-5-years test requires that you owned the home and used it as your main residence for at least 2 years out of the 5-year period ending on the sale date. The ownership and use periods don’t have to be the same 24 months, and the 2 years don’t need to be continuous — they just have to add up within that 5-year window.
You qualify for the full exclusion if:
- You owned the home for at least 2 of the last 5 years, and
- You lived in it as your primary residence for at least 2 of the last 5 years, and
- You haven’t already used the exclusion on another home sale in the past 2 years.
Married couples filing jointly can claim the full $500,000 if either spouse meets the ownership test and both meet the use test.
One boundary to keep in mind: this exclusion is only for your primary residence — the home you actually live in. A second home, a vacation property, or a pure rental doesn’t qualify for the Section 121 exclusion. If a property was part home and part rental, or you moved out and rented it before selling, the rules get more involved, and it’s worth confirming how the time counts before you rely on the full exclusion.
Worked example: a couple selling their home
Tom and Lisa are married filing jointly. They bought their home for $300,000, lived in it as their primary residence for 8 years, and just sold it for $760,000. Here’s the math:
- Sale price: $760,000
- Minus original cost: $300,000
- Gain: $460,000
- Their exclusion (MFJ): $500,000
Because their $460,000 gain is below the $500,000 exclusion, the entire gain is tax-free. Tom and Lisa owe $0 in federal tax on the sale. They met the 2-of-5-years test easily, and their whole gain fit under the joint exclusion.
What if your gain exceeds the exclusion?
If your gain is larger than your exclusion, only the amount above the exclusion is taxable — and it’s taxed at long-term capital gains rates if you owned the home more than a year. Say a couple bought for $250,000 and sold for $900,000: the gain is $650,000, the exclusion covers $500,000, and $150,000 is taxable.
That $150,000 is a long-term capital gain. For 2026, long-term rates for married joint filers work like this:
| 2026 long-term capital gains rate | Taxable income (MFJ) |
|---|---|
| 0% | up to $98,900 |
| 15% | up to $613,700 |
| 20% | above $613,700 |
If their taxable income places that gain in the 15% band, the tax is 15% × $150,000 = $22,500. Higher-income sellers may also owe an extra 3.8% net investment income tax. Keeping careful records of improvements raises your cost basis and shrinks the taxable slice.
Can you use the exclusion more than once?
Yes — you can use the home sale exclusion repeatedly over a lifetime, but generally not more than once every two years. If you claimed it on a sale within the past two years, you usually can’t claim the full exclusion again until that window passes.
This “once every two years” limit is what stops people from serially flipping primary residences tax-free. It resets over time, so a homeowner who moves every several years can use the exclusion again and again, just not on back-to-back sales inside a two-year span.
What should you do now?
If a home sale is on your horizon, a little planning protects a big chunk of money:
- Confirm you meet the 2-of-5-years test before you sell — a few months of residency can be the difference between tax-free and taxable.
- Gather your basis records: the purchase price, closing costs, and receipts for improvements. Every documented improvement lowers your taxable gain.
- Estimate the gain against your exclusion. If it’s under $250,000/$500,000, you’re likely clear; if it’s over, model the capital gains tax on the excess.
- Mind the two-year clock if you’ve sold another home recently.
A credentialed tax professional — like an IRS Enrolled Agent — can confirm you qualify and calculate any taxable gain before you sign a closing statement, when it’s far easier to plan.
FAQ
Do I have to buy another home to avoid the tax? No. That was an old rule that no longer exists. Today you simply exclude up to $250,000 of gain ($500,000 married filing jointly) if you meet the ownership and use tests — buying a replacement home is not required.
What if I only lived in the home 18 months? You generally won’t qualify for the full exclusion, which requires living in the home 2 of the last 5 years. Partial exclusions can apply for certain reasons such as a job relocation, health, or unforeseen circumstances — check IRS Topic 701 for the specifics.
How is gain above the exclusion taxed? Gain above your exclusion is a long-term capital gain if you owned the home more than a year, taxed at 0%, 15%, or 20% depending on your taxable income, plus a possible 3.8% net investment income tax for higher earners.
Can I use the exclusion more than once? Yes, but generally not more than once every two years. If you already claimed it on a home sale within the past two years, you usually can’t claim the full exclusion again until that period has passed.
Do I have to report the sale if all my gain is excluded? Sometimes. If the closing agent reports the sale to the IRS, you generally must report it on your return even if the gain is fully excluded. Keep records of your purchase price and improvements so you can prove your basis if asked.
